Description

Technical Field

[0001] The utility model relates to the technical field of rail transit, in particular to a linear photovoltaic sound barrier unit board. Background Technique

[0002] At present, the facade or flat roof components of sound barriers are mainly metal sound-absorbing panels and transparent sound-insulating windows, and their function is only to effectively control noise. However, single-functional materials are difficult to meet the needs of modern architecture and urban governance. The development trend of multi-functional composite materials is becoming increasingly obvious. By compounding materials with different functions, not only can the utilization efficiency of materials be improved, but also the use of one material for multiple purposes can be realized, saving resources and costs.

[0003] Therefore, in the fields of traffic noise control and building noise reduction, a "post-installed attachment type" photovoltaic sound barrier technology has emerged. This technology and product have initially achieved the goal of combining noise control and photovoltaic power generation technologies. However, the following technical problems also exist: 1. The above-mentioned photovoltaic sound barrier structure needs to attach and post-install photovoltaic panels on the existing sound barrier structure. The roof or facade designs of different sound barrier projects vary, and the installation of photovoltaic panels needs to be adapted to local conditions, increasing the complexity of design and construction; 2. Generally, only a single noise reduction or power generation function is achieved for the same area, reducing the effective utilization rate of building area. Content of the Utility Model

[0023] See also Figures 1 to 3 A linear photovoltaic sound barrier unit panel may include four E-shaped supports 10, a plurality of connectors 20, a microporous panel 30, a photovoltaic panel 40, a sound absorbing layer 70, and a plurality of C-shaped supports 80. The four E-shaped supports 10 may enclose a rectangular outer frame of the linear photovoltaic sound barrier unit panel, and the plurality of C-shaped supports 80 are connected and fixed to the E-shaped supports 10 on both sides of the rectangular outer frame, so that the plurality of C-shaped supports 80 may constitute the internal skeleton of the linear photovoltaic sound barrier unit panel. An open microporous panel 30 is provided on the outer side of the four E-shaped supports 10, and the microporous panel 30 is connected and fixed to the adjacent E-shaped supports 10 by a connector 20. The photovoltaic panel 40 is arranged on one side of the opening of the microporous panel 30, and the photovoltaic panel 40 is connected and fixed to the adjacent E-shaped supports 10 by a connector 20. In this embodiment, the light weight, high strength, and sound insulation characteristics of the photovoltaic panel 40 are utilized to replace the aluminum alloy back plate of the traditional metal sound absorbing panel. The internal skeleton is connected and fixed to the photovoltaic panel 40 or the sound absorbing layer 70 by means of a connector 20, and the internal skeleton can be used to provide auxiliary support to the photovoltaic panel 40 or the sound absorbing layer 70. A cavity 50 is formed between the enclosed structure of the four E-shaped supports 10, the microporous panel 30 and the photovoltaic panel 40, and the sound absorbing layer 70 is arranged in the cavity and the sound absorbing layer 70 is located in the groove of the four E-shaped supports 10 away from the opening side of the microporous panel 30. A certain gap can be left between the sound absorbing layer 70 and the photovoltaic panel 40 after installation and fixing. In this embodiment, the E-shaped support 10 provides the functions of top and bottom skeleton support, sealing plate, and separation of the photovoltaic panel 40 and the sound absorbing layer 70, and can assist in forming an internal cavity.

[0024] In this embodiment, the photovoltaic panel 40 can be a rigid photovoltaic panel. When installed, the photovoltaic panel 40 can be inserted into the grooves on the side of the four E-shaped supports 10 close to the opening of the microporous panel 30, and the connecting member 20 can be used to connect and fix the side wall of the photovoltaic panel 40 to the adjacent E-shaped support 10. Additionally, a sealing strip 60 can be filled and arranged in the gap between the photovoltaic panel 40 and the inner wall of the groove of the E-shaped support 10, so that the photovoltaic panel 40 and the E-shaped support 10 can be tightly connected and fixed.

[0025] In this embodiment, the photovoltaic panel 40 can also be a flexible photovoltaic panel. When installed, the photovoltaic panel 40 can be covered at the opening of the microporous panel 30, and then the connecting member 20 can be used to connect and fix the side of the photovoltaic panel 40 facing the adjacent E-shaped support 10 to the E-shaped support 10.

The linear photovoltaic sound barrier unit plate can be applied to the linear main frames such as the steel structure columns, beams and secondary structures of the vertical facade and flat slope roof of the sound barrier. The installation scope is wide; and the functions of photovoltaic power generation and sound absorption and insulation are combined together. One material has two functions at the same time, reducing the construction complexity and the amount of material used, and improving the space utilization rate; in addition, the integrated design and production can be realized at the same time, enhancing the integrity and stability of the product, and the integrated installation ensures the integrity of the photovoltaic panel and the main structure, avoiding the influence of the "post-installation of attachment type" process on the existing structure.
